* Contains data from the request, to be passed to the callback.
|

*
|
|
* Note: This implements ArrayAccess, and acts as an array of parameters when
|
|
* used in that manner. It does not use ArrayObject (as we cannot rely on SPL),
|
|
* so be aware it may have non-array behaviour in some cases.
|
|
*
|
|
* Note: When using features provided by ArrayAccess, be aware that WordPress deliberately
|
|
* does not distinguish between arguments of the same name for different request methods.
|
|
* For instance, in a request with `GET id=1` and `POST id=2`, `$request['id']` will equal
|
|
* 2 (`POST`) not 1 (`GET`). For more precision between request methods, use
|
|
* WP_REST_Request::get_body_params(), WP_REST_Request::get_url_params(), etc.
